How long have you use it? 3 years

Have you tried many other models before buying it: yes, I own or have tried almost everything that is equivalent.

What is so special that you love the most, the least:
+ +: Beyerdynamix quality (strength, finish, components, sound)
-: The cable a little stiff, the headphone could provide better insulation (compared to a DT770 or HD25)

This headset offers the sound quality of the famous DT-250.
Originally scheduled for commentators, it can also accommodate a keyboard or drums singer.
